Every post has an optional Starts on and Expires on date.
Starts on
The post will not be published before this date and time. Defaults to the moment you create the post. Useful if you want to schedule content in advance — create the post today but have it enter the queue next Monday.
Expires on
The post will not be published after this date and time. Once the expiry time passes, PostRecycle skips the post when selecting content to publish. The post remains in your library but goes inactive.
Leave Expires on empty if the post should remain active indefinitely.
All times are interpreted in your account timezone (see Settings).
